2 Claims. (Cl. 215-46) The present invention relates to new and useful improvements in closures particularly of the screw cap type for bottles, jars and other containers, and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising novel opening means.

Another very important object of the invention is to provide a container closureopener of the character described which is adapted to be expeditiously moved to either operative or inoperative position and which, when in the latter position, will be out of the way.

Other objects of the invention are to provide a container closure of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a vertical sectional view through a container closure constructed in accordance with the present invention, taken substantially on the line Il of Figure 2.

Figure 2 is a top plan view of the device.

Figure 3 is a fragmentary view in cross-section, taken substantially on the line 33 of Figure 1.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a screw cap I of suitable material which is adapted to be threaded on the usual neck 2 of a conventional jar 3.

Rigidly secured by rivets 4 to the top 5 of the screw cap I is a metallic strip or plate 6. Rising from one of the longitudinal edges of the metallic strip or plate 6 is an integral flange I. The inner end portion of the flange l is enlarged and formed to provide an apertured ear 8.

Pivotally mounted at 9 on the apertured ear 8 for swinging movement in a vertical plane is an opening bar or lever ID of suitable metal.

It is thought that the manner in which the invention functions will be readily apparent from a consideration of the foregoing. Briefly, the lever I0, when in inoperative position, rests with its free end on the top 5 of the screw cap I, as seen in full lines in Figure l of the drawing. When the screw cap I is to be removed from the jar 3, the lever Ill is swung on its pivot 9 and brought to rest on the metallic strip or plate 6 in side abutting engagement with the upstanding flange I, as suggested in dotted lines in Figure 1 of the drawing. It will be observed that when the lever I0 is in this position it projects beyond the periphery of the screw cap I where it may be conveniently gripped with one hand while the jar 3 is held with the other hand. The lever in is now forced against the flange 1 for unscrewing the cap I from the jar 3.

It is believed that the many advantages of a container closure embodying the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

l. A container closure comprising a screw cap, an upstanding flange mounted radially on said screw cap, and a lever pivotally mounted on one end portion of said flange and adapted for side abutting engagement therewith for unscrewing the cap.

2. A container closure comprising a screw cap including a top, a. metallic plate on said top, a flange rising from said plate and extending radially of the top, and a lever pivotally mounted on one end portion of the flange and adapted for side abutting engagement therewith, said lever, when in side abutting engagement with the flange, projecting beyond the periphery of the cap and providing means for unscrewing said cap.
